小麦产量的90～95%是通过光合作用制造的有机物质形成的.不少学者曾研究光照强度与籽粒形成、粒重增长的关系.但对光照强度与小麦生长发育的关系研究很少.本试验着重研究光照强度对春小麦发育速度以及产量构成因素的影响,不同生育阶段对光照强度的反应以及影响产量的关键时期,为进一步研究提高小麦对光能的利用率,制定稳产高产栽培技术提供理论依据.
90-95% of wheat yield is formed by photosynthesis of organic matter.Many scholars have studied the relationship between light intensity and grain formation and grain weight growth, but little research has been done on the relationship between light intensity and the growth and development of wheat. The experiment focused on the effects of light intensity on the growth and yield components of spring wheat, the response to light intensity at different growth stages and the critical period affecting the yield. In order to provide theoretical basis for further research on improving the utilization rate of light energy and establishing a stable and high-yielding cultivation technique in accordance with.
